Leak Detection Service
in Lehigh Valley
Hidden plumbing leaks can waste water and cause serious damage if left unchecked. A licensed plumber can confirm the source of the leak, identify the best access point, and outline clear repair options.
Signs You May Have a Hidden Leak
- Unexpected water bill increases with no change in usage
- Water stains on ceilings, walls, or baseboards
- Damp or warped flooring and soft spots underfoot
- Musty or moldy odors that don’t go away
- Low water pressure across multiple fixtures
- Sounds of running water when no fixtures are on
Common Leak Sources We Locate
- Slab leaks beneath concrete foundations
- Pipe leaks inside walls, ceilings, and floors
- Toilet leaks from tanks, supply lines, or seals
- Shower and tub leaks from valves or drain assemblies
- Fixture leaks under sinks and behind appliances
- Main water line leaks causing yard saturation or pressure loss
Tip: Check water bills regularly for unexpected increases. A hidden leak often reveals itself through gradual consumption changes long before visible water damage appears.

Hidden Water Leak
Detection
Not all leaks are visible. Some show up as high water bills, damp smells, or soft spots in floors. Technicians use professional leak detection tools, including acoustic listening devices and moisture meters, to locate leaking pipes behind walls, under slabs, and in hard-to-reach areas. Once the leak is found, they outline the best repair options to limit damage and restore normal water use.
Slab Leak Detection
& Repair
Leaks under a concrete slab can lead to structural issues and costly damage if not addressed. Plumbers in Lehigh Valley specialize in slab leak detection, using pressure testing and non-invasive locating methods to identify the problem area. Depending on the situation, they may recommend spot repair, rerouting lines, or partial repiping to fix the leak and protect your foundation.
Ceiling, Wall &
Bathroom Leak Repair
Water stains on ceilings, bubbling paint, or loose tiles in the bathroom often point to leaks from supply lines, valves, or plumbing fixtures. Experienced technicians trace moisture back to its source, repair the faulty connection or bathroom plumbing, and test the system to confirm the leak is gone. This focused approach helps limit demo work and reduces the risk of mold and further damage.
Leak Detection Costs
- Basic inspection: $150–$400
- Electronic leak detection: $300–$900
- Slab or underground leak locating: $600–$1,800+
Costs vary according to property layout and leak accessibility.
